To all whom it may concern,.-

Be it known that I, LOUIS W. NIMscHKE, of the city, county, and State ofNew York, have invented certain new and useful lmprovements in theManufacture of Brushes, of which the following is a specification.

This invention relates to certain improvements in the manufacture ofhair and other` brushes; and the invention consists of a brush of novelconstruction, as will appear more fully hereinafter, and finally bepointed out in the claim.

In. the accompanying drawings, Figures 1 and 3 representaverticallongitudinal section of the mold employed for filling thebaseplate of the brush with bristles. Fig. 2 is a top view of thebristle-hoiding'rbase-plate. Fig. 3 is a vertical longitudinal section'of a modified form of the filling-mold, and Fig; 4 is a verticallongitudinal section of the brushbase attached to a brush-back.

Similar letters of reference indicate corresponding parts.

In the drawings, A -represents a bristleholding base-plate, which formsthe novel feature of myimproved brush, and which is made of brass, tin,or other suitable soft metal, and of the shape and size of the brush tobe manufactured. The base-plate A is provided wit-h anumber of bent-uppoints or prongs, af, which are made integral with the body of thebaseplate and set into correspondingly-arranged 'socket-holes of thebase-block B of the mold- B. The base-block B is provided with verticalguide-pins b b, that are screwed into said block, said pins serving toguide the filling top block, B2, of the mold B. The base-plate A isprovided with a vnumber of perforations, d, which are provided withconically-tapering rims d', that project either from the under side orfrom the top of the base-plate A, as shown, respectively, in Figs. 1 and3. The top block, B2, of the mold B is provided with as many holes asthere are perforations in the base-plate A, said holes serving for thepurpose of filling the rimmed perforations d of the base-plate A withbristles. The baseblock B is provided vertically below and in line withthe fillin g-holes of the top block, and the perforations of thebase-plate with conically-tapering depressions d2, of such a na-I j turethat the inclination of their tapering sides is somewhat steeper thanthe inclination of the tapering rims, so that on lowering the top block,B2, by suitable pressure exerted thereon, the tapering rims of thebase-plate A are contracted at their edges by the depressions of thebase-block, and thereby the tufts of bristles that have been filledthrough 'the holes of the top block retained firmly by the contractedrims o f the base-plate A. This arrangement is shown in Fig. 1, in whichcase base-plates are produced in which the tapering rims project at theunder side of the plate and bind rigidly on the lower ends of the tufts.In place of arranging the tapering depressions on the base-block, theymay also be arranged at the lower ends of the fillingholesof the topblock, B2, as shown in Fig.

3, which arrangement is used when the tapering rims project from theupper partof the base-plate, as shown in Fig. 3. Inthis case theinclined sides of the tapering de-l pressions` are arranged at a smallerangle of inclination to the axis of the filling-holes than the outertapering surfaces of the rims to the axis of the perforations of thebase-plate A, so that on depressing the top block, B2, by suitablepressure, the edges of the tapering rims are contracted and closedtightly on the tufts of the bristles supplied through the openings ofthe top block, B2, to the rimmed perforations of the base-plate A. Thebase-plate Awith the tufts,`is then removed from the lling-mold andapplied by the spurs a a and a suitable layer of cement to a back, C,vof wood, rubber, or other suitable material, which back extends aroundthe base-plate, the rim of the brush-back being ilush with the face ofthe base-plate when the construction shown in Fig. 1 is used, while inthe construction of the base-plate shown in Fig. 3 the tapering andcontracted bristle-holding rims project above the face of the back.

This method of constructingbrushes is adapted to 'all kinds ofbrushes-such as hairbrushes, clothes brushes, blacking brushes, &c.-andproduces a cheap, strong, and durable brush, as the bristle-holdingbase-plate can be cheaply made of suitable cast metal, or pressed indies when metal of suflicient ductability and softness is employed.
